Sulfo-Cyanine 3 azide (A270274)

Sulfo-Cyanine 3 azide

Sulfo-Cyanine 3 azide is a water-soluble dye azide for Click Chemistry. Absorbance and emission of the dye are identical to Cy3® fluorophore. Brightness and photostability of fluorophore, together with high water solubility, makes this reagent an ideal choice for Click chemistry labeling of various molecules in aqueous phase. Click reaction can be carried out in pure water without need to use organic co-solvent. The reagent is designed for the labeling of sensitive molecules such as proteins, and even intact biological objects.
